What brown noise sounds like
Brown noise, also called red or Brownian noise, puts most of its energy in the low frequencies. It sounds like a strong waterfall heard from a distance, the inside of a plane or heavy steady rain. Because it has very little hiss, many people find it easier to listen to for hours than white noise.
It is popular for focus while working or studying and as a sleep sound. Play it under a Pomodoro timer to block out the room for each focus block.
Set and forget
Pick a timer and the sound fades out slowly at the end. The volume is low by default. The sound is generated live, so there is no loop point or repeating pattern to notice.
Brown, pink or white?
If white noise feels too sharp, brown noise is the gentlest of the three, and pink noise sits in between. You can switch between them while the sound plays and keep the one that feels right. The page remembers your last choice and volume.
